Department store Myer is at the centre of a worker rights campaign by Oxfam.
The charity group is urging consumers to contact new Myer CEO John King and demand greater transparency.
Myer has not yet signed the Bangladesh Fire and Building Safety Accord, according to Oxfam.
"Myer has so far refused to become more transparent and accountable by bringing factory locations out of hiding," the charity group said.
"Since the launch of What She Makes in October 2017, Myer have ignored requests to meet and talk with Oxfam representatives."
The group claims garment workers can receive as little as 36 cents an hour.
"They work hard to give their children a better life, but because brands like Myer allow poverty wages, they don’t earn enough to cover even the basics of life – food and decent shelter.
"Myer workers like these mums earn as little as 39 cents/hour, keeping them in poverty."
In response to the claims, a Myer spokesperson said the company has a policy in place that it expects all suppliers to follow.
"Myer expects all suppliers to adhere to our ethical sourcing policy to ensure ethical, safe and lawful manufacture and supply of merchandise."
The campaign follows a similar bid by charity group Baptist World Aid, which took aim at Decjuba last month.
